Proscan flatscreen tv displays test patterns

Friend of mine has the Proscan PLDED3257A-C Television. While moving the TV he left it plugged into the wall outlet. The cord became seperated from the TV casing and caused a short and pulled the connector from the board. I repaired the cord and when you turn on the TV is generates what look like different test patterns. Starting off with evenly spaced squares and so on to solid colors onto the off air signal (multiple colored bars arranged vertically). After about 7 minutes or so it make a horn kind of sound from the speakers. Any idea w.t.h. is going on with this?

SOURCE: proscan tv surround sound hook up

This depends on whether you have digital cable box or not. If you have a Digi Cable Box look for the red/white RCA output and connect this via RCA cable to the Red/White Audio input on your surround.

If just Basic Cable look for a red/white audio output on the back of your televison. connect this to the Red/white in on your surround. Could be called tv in or auxillary.

SOURCE: "No Signal" Message when using HDMI Inputs on 26" Proscan LCD TV

You MUST get HDMI Driver for your Video Card, it is NOT standard. You need to go to PC makers web site and download latest Video Divers for your PC, then you must set up Multiple Desktops, To do that you must first connect the TV, but leave OFF, connect up to PC, reboot, setup Video Card, turn ON TV, TV will have already been detected, On PC, Share the desktop, or Clone, whatever you wish, now reboot after saving settings. Now you set the TV for HDMI already and it should show you a desktop when chosen. You must select and setup TV, FIRST, then connect the PC. From then on, Turn the TV ON, then turn the PC ON, that way it will Always detect the HDMI port.

See if resetting the electronics to factory defaults cures the issue. If not, get some ear plugs till you have the main board replaced.

My 32" ProScan plded3257a-b won't turn on. Red indicator light turns yellow when power button pushed. Is this bad news for this trusty companion?

Hello John West,

I just checked MY first recommended SPARES dealer
(link will be at bottom: "SHOPJIMMY" for stock... on your
ProScan plded3257a-b... They are out-of-stock

WHICH MEANS MY 1st GUESS is a popular GUESS.

Your main POWERBOARD is divided into specific power sections... MOST LIKELY... you could open your set and (I DO NOT recommend) be able to measure... the PRINTED voltages around the out-put points WRITTEN around ON the Printed Circuit Board... (but these boards are in-expensive and the risk of injury is not worth the POTENTIAL savings
(assuming you have the requisite skills & materials).

Always check your OWN BOARD NUMBERS...!!!

Never force any connections...!!

Take lots of pictures ... put EVERYTHING EXACTLY BACK.

My first and ALWAYS recommendation... always protect delicate SEMI-CONDUCTORS by wearing anti-static wrist straps... A tiny static spark you might not feel is sufficient to RUIN the diodes in your cars ALTERNATOR (honest... for reals).

Second serious precaution... Use shopjimmy, amazon, eBay or worse... (at page bottom)

Never rely on anything but your OWN circuit board numbers.

Serious ELECTRONIC technicians always take STATIC PRECAUTIONS... and turn off the power (when-ever possible).

It is not improbable that the mainboard is your issue...
but compared to a "QUALIFIED" (good) home repair technician...

It is a mistake you can afford about 5 more times...
and if you can go BACK to your ORIGINAL FAILURE condition... you are doing fine (excellent start)...

Most "home technicians" aren't even good.

As far as I'm concerned... these packs are too cheap to recommend live power tests (YOU can get seriously ZAPPED)...

If the POWER BOARD does not immediately power up... I would suggest you assume 1 (one) of two (2) things...

1. Your "NEW" board is also bad (or you did not try to select "sources" when you installed it... (been there.. did that).

2. It was actually your MAIN-BOARD that needed to be replaced.

Buy one.... TRY IT.

Hey... if you like the set... so you end up with a couple of spare packs... properly handled & stored they will only appreciate in value).

Ill-advised activity... (voltage testing)

If you own a decent volt meter...
and you can look CLOSELY at the TEST POINTS... YOUR POWER BOARD voltages are printed on the circuit-board OUTPUTS:

Just keep in mind... you can get hurt... while causing more damage... with careless handling!!

Take photos... Work safely... Check your numbers and
ALWAYS wear ESD (static) wrist bands...

How do you repair or replace powersupply on proscan modwl plded3273a

Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.

Vizio plasma Tv Model P42Hd ,Tv has gone into some sort of test pattern on screen, has a color band of several colors from left to right on screen. The colors move up and take the position of the one...

with set unplugged, hold down channel up and down on the front panel at the same time while you plug the set in. Power light will go amber like it is in the off mode and when you hit the power button the set should come up and be normal.
